Kapteos introduces the fourth generation of its eoSense™ optoelectronic converter, offering significant upgrades in usability, precision, and robustness. Designed for integration into advanced EM-field measurement systems, this new generation delivers higher accuracy, simplified setup, and enhanced shielding performance.
Key improvements in the 4th Generation
- Automatic probe recognition for faster setup
- Automatic AF adjustment at frequency of interest
- 2× more accurate probe axis orientation
- Ruggedized optical connector (MIL-38999)
- No external computer required – fully self-contained operation
- Extended low-frequency range down to 10 Hz for LF model (5× lower)
- Up to 3 RF sub-bands for SHF model
- Improved shielding effectiveness: +30 dB from 1–10 GHz
- Separate calibration of probes and converters
- Direct AWG and ASA control as a software option

Optimized for complex test environments
The eoSense™ 4th Generation has been engineered for seamless integration into multi-converter test benches with dozens of EM-field probes. It’s ready for future H-field optical probes and features rugged construction for long-term reliability in laboratory and industrial setups.
